Mirame360 modifications:
- Changed absolute imports to package-relative imports so spatialmedia can be
  safely vendored under mirame360_metadata.
- Corrected an uppercase constant reference in unknown spherical XML handling.
- Inserted st3d/sv3d boxes before trailing optional VisualSampleEntry boxes,
  as required by the Spherical Video V2 RFC.
- Corrected pose_yaw_degress to pose_yaw_degrees while parsing prhd boxes.
  This typo is present in the upstream revision identified above.
